On walls and floors, we do not allow staples, nails, screws, or duct tape. If you want to hang anything, please use 3M command hooks. We do not allow glitter, confetti, cornmeal, loose straw, dark flower petals, mylar balloons, dried flowers, sprinkles, or non-biodegradable products. If you have decorations you want to use, but are unsure if they’re welcome, please contact us for clarification.
